Rio Ferdinand has said that he is not happy with what he has won so far in his career.

Since joining Manchester United in 2002, the defender has won the Premier League six times, as well as earning two victories in the FA Cup, securing a Champions League title and winning the Club World Cup.

"I'm not happy with what I have won, not when I can look around at people in the changing room and know they have got more than me," Sky Sports News quotes the 34-year-old as saying.

"You always aim for the people above. That is what I did the day I walked through the door. I looked around and saw people with three, four, five titles and thought 'I want to have that'.

"You set yourself targets all the time. I am never going to sit in that changing room and think 'I am happy with what I have done'."

Ferdinand's testimonial takes place against Sevilla in August.
